4 Sheets-Sheet 4 APPARATUS FOR MAKING BUNDLES FROM THE STREAM OF PRINTEDSHEETS IN ROLLING PRESS BACKGROUND, OBJECTS AND SUMMARY OF THE INVENTIONThis invention relates to an apparatus for making bundles from thestream of printed sheets in a rolling press in the best order with anextremely simplified motion so as -to be suitably used with asuperhigh-speed running rolling press. In the ordinary machine, there isprovided a vertical passage into which the stream of folded sheets isdelivered through an interruption plate and drops to the bottom. A turntable is provided that turns as far as 180 for every predeterminednumber of sheets arrived. In such an arrangement, especially in the casewhere the predetermined number of sheets is large, the pile becomesconsiderably thick at the side of folded edges, so as to make an orderlyaccumulation difficult.

To remove such defect, several prior art devices were offered. One ofsuch devices intended the use of a plate which changes inclinationgradually during accumulation on it. Another device used a plate whichcarries the sheets downward little by little on a turn table. However,such devices can not be used for high-speed printing, chiefly because ofthe complicated construction and movement.

The object of this invention is to provide an apparatus which enables anorderly accumulation of sheets by an extremely simplified motion of theparts.

According to this invention the above requirements can be attained by asimple construction and with an extremely simplified motion.

Such construction and movement together with the advantages obtainedthereby will be readily understood by one skilled in the art from thefollowing description taken in connection with the accompanyingdrawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of a workingexample partly in section;

FIG. 2 is the side view in section taken along the line 2, 2 of FIG. 1;and

FIGv 3 to FIG. 6.illustrate the function of this invention in order.

- DESCRIPTION OF THE PREFERRED EMBODIMENT In the drawings, passage 7, ofthe apparatus is enclosed by rear walls 8, 8 and front walls 9, 9acceptsdelivery of printed sheets in a stream. Turn table 10 issituated at thebottom of said passage 7 upon which bundles A, B, C, are piled to form astack. The turn table 10 is turned about pivot. 11. The apparatus isprovided with nipping rolls 12, 12 and conveyor belts 13, 13'. A row offront. sheets is delivered in layers with folded edges in front. Aninterruption plate 15 situated at one side, the upper position of whichis made to interruptthe stream when a definite number of sheets haspassed by a signal from a counter head located at the delivery end. Arelay plate 16 is positioned under the interruption plate 15 but in theother A makeup plate 17 upon which the sheets are accumulated until theyform a bundle is situated just under the relay plate 16. but in oneside. There are pivot bars 18, 19, to which the plates 15, 16, 17 arerigidly fixed respectively. Side members 21, 21' are in pairs forming amovable frame supporting both ends of the pivot bars l8, l9 and 20respectively. Pivot bar 18 is supported rotatably but pivot bars 19 and20 are rigidly supported on the frame when working. Guide bars 22, 22are used to guide the go and return motion of the movable frame. Slidebearings 23, 23 and 24, 24' are provided on the frame through which theframe is guided by the guide bars 22, 22 when it is moved.

Brackets 25, 25', 26, 26' fixing both ends of the guide bars in pair tothe machine frame 27, 27'. The fixing points of the brackets are madepreferably adjustable so as to adjust the moving direction of themovable frame when required. Oil

pressure cylinders 28, 28 are fixed on the machine frame, and carriespiston rods 29, 29' which are connected to said bearings 23, 23respectively.

A rocking arm 30 is rigidly fixed to the end of pivot bar 18 whichcarries interruption plate 15. Aroller 31 touches the curved surface ofcam 32 by the action of a tension spring 33. A stop pin 34 is used tolimit the downward position of the cam 32. A rocking arm 36 with pivot35 is connected integrally with cam 32 so as to form bell crank arms. Anelectromagnet 37 is used to move the arm 36 through the plunger 38,thereby moving the interruption plate 15.

OPERATION OF THE INVENTION Starting at the state shown in FIG. 5, withthe relay plate 16 in the passage 7, electromagnet 37 raises theinterruption plate 15 to its uppermost position and at the same time,the movable frame carrying the three plates 15, 16, 17 is moved rearward(rightward facing the drawing) as shown in FIG. 6 by the action of thecylinders 28, 28' through piston rods 29, 29, slide bearings 23, 23' andguide bars 22, 22'.

The relay plate 16, fixed onthe frame through pivot bar 19, is thenmoved out of the passage 7, and makeup plate 17, fixed on the framethrough pivot bar 20, is made to enter the passage 7 so as to receivethe sheets which have been accumulated on the relay plate by the aid ofthe rear wall 8. The stream of printed sheets is made to accumulate onthe makeup plate 17 (see FIG. 6). While the accumulation proceeds andwhen a definite number of sheets forming a bundle have passed a counterhead positioned at the delivery end (not shown in the drawing), theelectromagnet 37 is demagnetized by a signaling from the counter headand the cam is moved to its lowermost position pulled, by a spring 33until the cam touches the stop pin 34. Then the lever 30 falls rightwarddown together with the plate 15, interrupting the stream of sheetsbefore the head of them before a second new bundle will pass there. Thusthe stream will be now accumulated on the interruption plate 15 (seeFIG. 3).

While the stream of sheets are accumulated on the interruption plate 15,the frame is removed to the frontward position (leftward facing thedrawing) carrying all said three plates 15 16, 17 by reversing theaction of the driving system, removing the plates 15 and 16 out of thepassage and making the relay plate 16 enter into the passage 7 again. Atthe same time, the interruption plate 15 is lowered down to the samelevel as the relay plate 16 by the sliding down movement of the roller31 along the curved surface of the cam 32, thus removing the sheetsaccumulated thereon on to the relay plate 16 by the cooperation of thefront wall 9 (see FIG. 5). During the same motion of the movable frame,while the makeup plate 17 is also removed out of the passage, the sheetsupon it which must be at a definite number so as to make up a bundle aredropped upon the turn table 10 down by the aid of front wall 9, wherethe preceding bundle A has been already turned The operation statedaboveis repeated dividing the printed sheets into a definite number andmaking bundle therewith quickly and orderly.

Thus, it can be seen that the objects of the present invention areachieved by the use of an interruption plate made to rock up and down, arelay plate and makeup plate, all supported on a movable frame which ismade to perform a go and return motion along a straight line, thedirection of which is adjustable according to the thickness of thefolded edge of the printed sheets, and that the construction is sosimple and the motion of the moving parts is so'extremely simplifiedthat nodefect or mistake can take place for accomplishing the orderlydivision of the printed sheets and making correct bundles automatica'llyand quickly to match the operation of the super highspeed rolling press.

Obviously, the embodiment shown is exemplary only and a.

wide variety of embodiments may be devised without departing from thespirit and scope of the invention.
